Gram-positive, feebly motile rods, 0.5-0.8 x 4.0-8.0 µm. Subterminally / paracentrally,
ellipsoidal to cylindrical endospores in unswollen sporangia are formed.
ellipsoidal to cylindrical endospores in unswollen sporangia are formed.
Colonies are low convex, circular and slightly irregular, opaque, creamy-brown,
smooth, glossy, 3-10 mm in diameter. Moderately thermoacidophilic. Best growing
and sporulating at pH 5.5 and 50 ºC on nutrient-weak media such as BFA (Logan et
al., 2000) and BFA at half nutrient-strength; growing and sporulating weakly on
trypticase soy agar containing 5 mg/l MnSO4. Minimum pH for growth 4-4.5
Aerobic. No growth at pH 7 or above. Growth temperature 30 to 55 ºC. Allantoin, urate
or NaCl are not required for growth.
